    Clamp Meter VS. Multimeter

    Clamp meters are divided into mechanical pointer clamp meters and digital clamp meters. Its biggest advantage is that it can measure the current in the line without disconnecting the line to be measured. The current multi-function clamp meter also carries test leads and other voltage resistance gears, and can also be used as a multimeter, and the clamp current meter is also divided into pointer type and digital type, which are roughly the same as the multimeter classification, but the clamp meter head has a transformer, so it is more troublesome to carry.

    How Does a Clamp Meter Work?

    As one of the necessary test tools in daily maintenance work, the clamp meter is mainly used to test related parameters such as voltage, current, frequency, etc. It is required to have high test resolution, test accuracy and more test functions. Clamp meter is an instrument that integrates current and ammeter. It is an important branch of digital. Its working principle is the same as that for measuring current.

    How to Use a Clamp Meter?

    The digital clamp meter is a meter used to measure the current of the running electrical circuit. With this instrument, the current can be measured under uninterrupted power conditions. It can be used to measure AC and DC voltage, AC current, resistance, capacitance, diode forward voltage drop, circuit continuity, frequency and duty cycle. The greatest convenience of measuring AC current is that only one wire to be measured is placed in the intersection. Moreover, the measured AC current frequency range can be as wide as 1 kHz. The display of ATO clamp meter is equipped with background light, which is convenient for working under the condition of low light.
